PulpCleaner.com | Premium Cleaner Parts for Paper Mills

Engineered for Reliability

Qingdao Naiwell Paper Machinery Co., Ltd. is a multifunctional plastic product manufacturer located in Qingdao, Shandong. We specialize in producing high-tech thermoplastic products using advanced injection molding technology.

Our client base includes paper mills operating Valmet, GL&V, Andritz, Kadant, and Voith cleaners. Since spinning off our papermaking service business in 2016, Naiwell Paper Machinery has operated independently with a focus on innovation and quality.

As a family-owned enterprise with roots tracing back to the early 1990s, we purchased our first injection molding machine and began plastics operations that continue to evolve today.
